{
var p = document.createElement("p");
var select1 = document.createElement("select");
select1.name = "select";
select1.onchange=onSelChange;
var n = 0;
select1.options[n++] = new Option(n, n);
select1.options[n++] = new Option(n, n);
select1.options[n++] = new Option(n, n);
select1.options[n++] = new Option(n, n);
p.appendChild(select1);
form.appendChild(p);

<script type="text/javascript">

function onSelChange()

{

alert('');

}

function onSelChange2(t)

{

alert("onSelChange2 " + t);

}

function AddSel(form)

{

var p = document.createElement("p");

var select1 = document.createElement("select");

select1.name = "select";

var cc="aaa"

select1.onchange=new Function("onSelChange2('"+cc+"')");

var n = 0;

select1.options[n++] = new Option(n, n);

select1.options[n++] = new Option(n, n);

select1.options[n++] = new Option(n, n);

select1.options[n++] = new Option(n, n);

p.appendChild(select1);

document.forms[0].appendChild(p);

}

</script>
